<p>PURPOSE: To provide a buried prosthesis which is guided forward in an expanded alveolus and sufficiently held only in an alveolar bone without forming a deep hole for penetrating a alveolar bottom part to reach the inside of a jaw bone. This buried prosthesis is stabilized in the alveolar bone between fang only by the maximum rotation of about 90 deg.. CONSTITUTION: In a buried prosthesis having a shaft part and a conical holding part, a plurality of wedge-like and sickle-like holding blades 3 are formed as buried projecting parts in the holding part. Further, the holding blades 3 are disposed in the holding part 1 to fact each other for each pair.</p> |
